Application led February 18, 192.1. jSerial No. 446,031. l

.. whereby the dust and dirt may be swept thereinto from the floor, the.opening being provided with a closure, and the chute being alsopreferably provided vwith a4 receptacle Yin another part of thebuildingfor receiving the dust and dirt, and which receptacle is adapted to beremoved when desired.

To the attainment of these ends and the accomplishment of other new andusefulobjects as will appear, the invention consists A inthe features ofnovelty in substantially the construction, combination and arrangementofthe several parts hereinafter more fully described and claimed and shownin the accompanying drawing illustrating this invention, and inwhichligiire 1 is a vertical, longitudinal sectional view showing thechute in position within a wall and constructed so as to receive dustand dirt from a' plurality of floors at different elevations. l

Figure 2 is an enlarged detail sectional view vof the entrance end ofthe chute. y Figure' is an enlarged view partly in front elevation andpartly in section.

Figure 4 is a detail perspective view vshowing the position of thechute.

Referring more particularly to the draw-v ing the numeral 10, designatesthe outer wall and 11 the space within the wall and' in which space thechute or collector is arranged.'

12 designates a chute of any desired size and configuration,preferablyconstructed of some thin metallic substance and may be -held in positionin any desired or suitable manner such as by means of fasteningxdevices(not shown) which may pass through vany of the walls of the chutetoengage a suitable support or anchor. l

Vvln the form of the invention herein shown this chute is arranged toextend for a considerable distance within the wall so as to receive thedust and dirt from a plurality of superposed floors.

The chute is provided with an entrance opening adj acent each of thefloors 13414e- 15, 4and these entrance openings are on a line with thefloor. Y

The chute is preferablyiprovided with a Closed top 16 and a plurality OfPartitions 17--18 dividing the chute into a` plurality of passages19-20-21. Each of these pasf sages communicates with the respectiveinlet opening adjacent the respective floors 13- 14e-15sothat the dustand dirt swept into the passage from anyone of the floors will not bedischarged into the passage leading from Vthe neXt lower floor and thislwill thereby prevent the dustand dirt frombeing de liveredto theVfloor'below ythrough the en-j" trance opening of fthe chute.

' The top ofthe partition 17, is preferably deflected as at22, so as tobe in alinement with. the top of the floor 13, while the top of' thepartition 18, isdeflected as at 23, for a similar purpose. A n

' The front wall'24, ofthe chute `adjacent the upper inletgopening isdeflected as at 25, so as to project beneath the floor 13, to assist inholding the chute in position. The portion-of the wall 24, adj acent'the inletv opening at the floor line 1,4, is also deflected as at 26, toproject beneath the floor while theportion of the front wall24,'adjacent the-openiing at the floor line 15, is deflected as at 27,to standflush with the top of the floor 15.

It will thus be seen thatwith this construction and whenthe dirt isswept into the chutejfrom any floor it will be conveyed through therespective passages to be deliv ered preferably to a'receptacle 28,which is removably. supported within the chute adjacent the bottomthereof and intojwhich 'chute the passages 19-201-21vdischarge`."

A hood-like member 29 is provided'for each of the inlet openings of thechute and as the construction of each of these members is the "same thedescriptionof one will apply equally as well to them all.

This member 29, is provided with an open rear end 30, having slots 31,in the side wallsH thereof and which slots openthroughv thev end 30.

Therfront of the hoodis open as at 32, and v i ceptacle 28.

posite sides thereof are guides 34, and these guides are Hush with thefloor lineso that,

when the hood 29 is inserted into the inlet opening of the chute thefront end of the hood Will rest upon the floor and the head Will besupported by the guides 34. Fastening devices 35, are connected with theWall of the chute and project into the openings 3l,.as the hood isplaced in position. Co-operating with the fastening devices 35, arethumb nuts 36, which are accessible from the inside of the hood so thatwhen the hood is in position and the flange 3l abuts the outer face ofthe wall lO, the thumb nuts .36, may be adjusted to clamp the hood inposition and thereby hold the flange 33 against the face ofthe Wall.This will obviate the use of fastening devices on the outside of thehood and will also permit the hood to be readily removed and placed inposition When desired. Y

A closure 37, is provided for-the open end 32,? of the hood and thisclosure is preferably pivot-ally mounted as at 38, and is providedwith ahandle 39, means of Which the closure may be swung about its pivot. As ameans for normally holding the closure in a closed position, :suitablesprings 40, may be provided. In use, when the dust and dirt` has beengathered at a point adj aeent the closure 37, the latter may be openedand the dust and dirtsweptinto the chute-so Vthat it Will drop throughthe respective passages into the rel/Vhen the closure 37, is releasedythe springs .a0-Will close the saine.

lVith this improved construction it Will be. manifest that the sameymay4 be` readily applied to any buildingl vhaving a space Within itsWall and when applied the necessity of exterior fastening devices Willbe obviated. Obviously the chute may be constructed to accommodate anydesired number of floors.,

`While the lpreferred form of the invention hasfbeen herein shown anddescribed, it is y to be understood that various changes may be made inthe details of-construction and in thecombination andarrangement of theseveral parts Within the scope of the claims, Without departing from thespiritof this invention. f
